To all whom it mag concern:

of the- King of Norway, and residing at E'dgewoocl Park, in the countyof Allegheny and State of Pennsylvania, United States of America, haveinvented certain new-and useful Improvements in Apparatus for the Con-'trol of Railway Cars or Trains,of which the following is aspecification.

.My invention relates to apparatus for the control of railway cars ortrains. Y I will describe one form of apparatus embodying my invention,and their point out the novel featuresthereof'in claims.

my co-pending application filed December 18', 1911, Serial No. 666,394.

In the accompanying drawings, Figure 1 is" a view showing in sideelevation a-portion of a railway car having applied theret oneformofcontrolling apparatus embodying my invention. Fig. 2 is a view showinginend elevation the car and apparatus shown in Fig. 1-. Fig. 3 is a Viewshowing on a larger scale a portion of the apparatus shown in thepreceding views. Similar reference characters refer to simi-- lar partsin each of the several views.

Referring, to the drawings, 10 designates a railway car: This'car isequipped with-"a fluid pressure braking system comprising as usual abrake pipe 47 It is understood that a reduction of pressure in thisbrake pipe causes an application of the brakes.

Connected with the brake pipe 47 by means of a pipe 12 is a valve device11. This valve device may be of any suitable type, which, when opened,remains open until the" pressure in the brake pipe 47 falls to a certainvalue. One form of valve device of this character is shown and describedin my copending application, Serial No. 666,394, filed December 18,1911, of which the present application is a division. This valve device11 is operated by means of a tripping device 13 when the tripping deviceis actuated by a stop arm 14, as hereinafter explained; the trippingdevice is illustrated on a larger scale in Fig. 3. The stop arm 14 islocated adjacent the trackway and is arranged to be moved into and outof position for actuating the trippingdevice 13. As here shown, thisstop arm is pivoted to a railway signal sema- Minis-suspended from theblade 16 of the semaphore by means of afiexible connection 17 such-as achain. The stop arm is prefer-j ably of flexible material to perm-itbending Patented J uly 28,1914.-. 1 Originalapplicatiom filed; December18-, 1911,! Serial No. 6681394: Divided! and this application'fild Marchin a vertical plane. The semaphore here.

shown isof the upper'quadrant type; when the semaphore is in thehorizontal: or

dangerposi tion the stop 14 is. in position to actuate the trippingdeviceya-ndwhen the semaphore moves upwardly to caution or clear"position, theystop' arm is moved? upwa-rdly out ofjposition forengagement with ppiing'device. i The present application is a divisionof The valve device 11 is operated by means of a shaft which is mountedto oscillate 1n--'bearingscarriedi-n a shaft housing 38,-

which housing is mounted in the inclos'ing casing of the valve device11. Rigidly se cured to the shaft 37 at its outer end by meansiof a pin37 isian' arm- 39 (see Fig. 3) which I will hereinafter term a trip-arm,

andwhiclris arranged to be operated" by the 1 stop arni 14Referring-particularly to Fig.

3, it will 'beseen that the end ofthe housing38 is slit and unr'oll'ed,forming a tongue 40 which is located over the trip arm-391 Rigidlysecured to-this tongue by means of rivets is a plate 41 of comparativelystiff, material such as-xcold rolled-steel, also a strip 42, 'ofresilient material preferably" 7 The end of strip '42pr'esses downwardlyupon the tri'p-arm 39, thereby biasing thel'a'tter toward ablock'44 fSecured to the outerend of plate"4-1 isa strip" spring steel.

43 of resilient material, alsopreferably of spring steel, which stripbears againstthe' end: ofzthehonsi ng 38 as shown. This strip 43preferably is providedwith an extension 43 which passes between the triparm 39 and the block 44. This extension 43 protects the arm 39 fromdirect blows of arm 14, but exerts no, pressure on the trip arm 39.Mounted on the vehicle 10 are two inclined surfaces 45 and 46 facingrespectively I toward and away fromthe direction of nor- A I malmovement of the vehicle. The block 44 is fixed on the inclined surface45. These surfaces are so arranged that the strips 42 and 43 and thetrip arm 39 all cross the inclined surface 45 and pass below surface 46.Assume now that the vehicle 10 is moving in thedirection indicated bythe arrows in Figs. 1 and 3, and that it approaches a stop arm 14 in theoperative position. If the relative positions of the vehicle and thestop arm are correct, the stop arm will be struck by the strip extension43 and will pass between this strip and the inclined face 45, therebyraising this strip from the block 44. The strip 43 in turn raises triparm 39 thereby turning the shaft 37 and operating the valve device 11.If the relative positions of the vehicle and the stop arm are such thatthe stop arm is not struck first by the extension 43*, then the arm willbe engaged by either the strip 43 or the inclined plane 45 and will beguided by one or the other toward the strip 43 After the strip 43 passesthe stop arm 14, this strip will spring back against the block 44, andthe trip arm will be moved back against this strip by gravity and by theaction of the spring strip 42. The purpose of the inclined surfaces 45and 43 1s to compensate for the vertical motion of the vehicle and forany irregularity in the position of the stop arm 14. It will be seenthat if the vehicle moves in the direction opposite to that indicated bythe arrow in Fig. l and passes a stop arm 14 in operative position, thestop arm will ride upwardly on inclined surface 46 and also on theinclined plane formed by strip 42 and plate 41, and will, therefore, notmove trip arm 39.

Although I have herein shown and de scribed only one form of apparatusembodying my invention, it is understood that various modifications maybe made therein within the scope of the appended claims withoutdeparting from the spirit and scope of my invention.

Having thus described my invention, what I claim is: v

1. In combination, a railway vehicle, a trip arm mounted upon thevehicle, means on the vehicle adapted to be operated by the trip arm, astop arm mounted adjacent the trackway to operate the trip arm, aninclined surface carried by the vehicle for guiding the stop arm intoposition for operation of the trip arm when the vehicle moves in onedirection, and another inclined surface carried by the vehicle forguiding the stop arm out of position for operation of the trip arm whenthe vehicle moves in the other direction.

2. In combination, a railway vehicle, a trip arm mounted upon thevehicle,means on the vehicle adapted to be operated by said trip arm, astop arm mounted adjacent the trackway to operate the trip arm, twointersecting inclined surfaces mounted on the vehicle with their acuteangle opening toward thedirection of trafiic for guiding the stop arminto position to operate the trip arm when the vehicle moves in onedirection, and a third inclined surface mounted upon the vehicle forguiding the stop arm out of position to operate the trip arm when thevehicle moves in the other direction.

3. In combination, a railway vehicle, two members mounted thereon toform anacute angle opening in the normal direction of movement of thevehicle, one of which members is fixed and the other movable, a stop armmounted adjacent the trackway and adapted to pass between said membersthereby moving the movable member, and means on the vehicle operated bysaid movable member.

4. In combination, a railway vehicle, a trip arm mounted on the vehicle,means on the vehicle controlled by said arm, a stop arm mounted adjacentthe trackway, means on the vehicle for guiding the stop arm intoposition for operatlon of the trip arm when the vehicle moves in onedirection, and

means on the vehicle for guiding the stop arm out of position foroperation of the trip arm when the vehicle moves in the other direction.

In witness whereof, I aflix my signature in presence of two Witnesses.

PER UTNE.
